TILBER J'. PINE, OF GSEKOSH, VJISCONSIN, ASSIGNOR TO PINE-IHRIG MACHINECOMPANY, OF OSHKOSH, WISCONSN, A CGRPORATION OF VJISCONSIN.

COILER-MAKING MACHINE.

Application filed October 31, 1905.

To all whom it may concern:

Be it known that l, VILBER J. PINE, a citizen of the United States,residing at Oshkosh, in the county of `Winnebago and State of1Wisconsin, have invented a new and useful Geiler-Making Machine, ofwhich the following is a specification.

My invention relates to a machine for making coilers which are used incoiledwire fabric machines, and the object thereof is to produce amachine capable of making coilers which shall not only be uniform, butshall also be absolutely accurate for the purpose of properly ceilingwire.

One of the principal difficulties attending the use of coiled-wirefabric machines arises from the fact that the coilers employed lackuniformity and moreover are not perfect or accurate in the grooves orcuts through which the wire passes in the formationor production of thecoil, with the result that the coils of the wire fabric likewise lackuniformity and perfect-ion, besides which the coilers soon become wornout and useless because of the friction between the wire and the groovedue to the imperfections or inaccuracies in the path formed by suchgroove.

For the purpose of making absolutely perfect and accurate coilers,perfect duplicates of one another, l yhave designed a special machineforming the subject matter of this invention, by the use of whichmachine any number of exactly similar coilers may be produced with anaccurate groove according to a predetermined form or templet.

In the drawings, Figure l is a plan view of my coiler making machine;YFig. 2 a side elevation thereof; lfig. 3 an end elevation partly brokenaway; Fig. 4 a section on the lino eL-fl of Fig. l; Fig. 5 alongitudinal section of the arbor and associated parts taken on line ofli ig. l; and Fig. 6 a detail view of the inner end of the arbor andillustrating a. completed coiler just before being cut off from theblank stock.

Referring to the present embodiment of my invention as herein shown, themachine provided with a main frame or bed plate l, which may besupported in any suitable manner and lwhich is arranged to carry orsupport the working parts of the machine. These working parts aremounted on a slide or base plate Q adapted to slide longitudinally ofthe machine in suitable grooves in Specification of Letters Patent.

Serial No. 285,311.

the main frame thereof, as indicated in Figs. l and 3. Rising from themain frame is a stationary support or bracket 3 provided with bearingst, in which are journaled the rotatable and also longitudinally movablearbor or shaft 5. This arbor is hollow so as to receive the rod or blankstock 6, from which the coilers are t-o be formed. The outer end of thearbor 5 is supported in a longitudinally movable frame 7, which issecured in suitable manner to the slide 2, with the result that as theslide moves the frame 7 and its arbor 5 are correspondingly moved, suchmovement being longitudinally of the machine. The arbor carries towardits outer end the templet 8 which as shown has a spiral grooveterminating or running into a straight or longitudinal groove as isrequired in coilers for the purposes already explained, such templetrepresenting an exact counterpart of the character of groove to be cutinthe blank stock in the manner hereinafter explained.

It will be understood that the arbor 5, together with its rod or blankstock G must be rotated for the formation of the spiral cut and have asimultaneous longitudinal movement and must have a longitudinal movementonly at the time when the longitudinal groove for the coiler is to beformed. The means for so operating the arbor will now be described.

For the purpose of moving the arbor and the blank stock longitudinallysimultaneously with th-e rotation of the arbor and for so moving thearbor longitudinally in degree as determined by the templet, I provide astud or roller 9 having a fixed position with relation to thelongitudinal axis of the machine and adapted to be received both by thespiral and the straight portion of the groove in the templet. This'roller is mounted or supported in suitable manner but in the presentinstance thesame is carried at tbe inner end of a bracket plate l0,adjust-able transversely of the machine, as hereinafter described. Whenthe roller occupies its position at the outer end of the spiral groove,as seen in Fig. 2. the arbor is in the proper position for the beginningof the cut on the blank stock. whereas when the roller reaches the endof the straight cut. the end of the eut on the blank stock has beenreached. Suitable arrangement is made for withdrawing the roller 1G fromlPatented Dec. il?, i912. e

the templet and in the present instance such arrangement consists of aslide 11, on which the plate 10 is mounted, and which is arranged to beadjusted transversely of the machine by means of the screw 12, providedat its outer end wit-h the handle 13.

Referring next to the means for rot-ating the arbor in the operation offorming or cutting the blank stock to produce the coilers, I mount uponthe arbor 5 a gear 14- having a spline or key connection therewith. Asclearly shown in F 5, this gear is restrained againstlongitudinalmovement of the machine by means of an extension 3 on the bracket 3,which extension partially envelops the gear and thus preventslongitudinal movement thereof. lithin the hub portion of the bracket 8and surrounding the arbor is a sleeve or bushing 15 having alongitudinal slot to receive the spline or key 16. This key is ofpeculiar formation, in that it is reduced in thickness toward its innerend, leaving its outer end, that is t-he end toward the left in Fig. ofthe full height, so that its upper edge is flush with the outer surfaceof the bushing 15. This key, which is arranged to slide longitudinallyin the key-way or seat 17 of the arbor, is adapted to enter at its outerend the gear 14 at which time such gear is operatively` connected withthe arbor to thereby rotate the latter whenever the gear is rotated inthe manner hereinafter explained. At its inner end, which extends beyondthe inner face of the bracket 3 the key is securedV to a suitableoperating device, such as a collar 17, whereby the key may be manuallymanipulated whenever it is desired to disconnect the gear from the arborand to connect such arbor with a pulley 18. TWhen the key is thusshifted longitudinally and inwardly the inner or enlarged end of the keyis arranged to be received in a key-way or seat 19 in such pulley, withthe result that upon disengagement of the key from the gear 14 operativeengagement between the arbor and the pulley 18 is brought about. Thisengagement of the pulley with the arbor takes place after the coiler hasbeen completely formed and when it is desired to cut off the coiler fromthe blank stock in a manner hereinafter explained when the tool forcutting the groove in the coiler is described.

To rotate the gear 14- at the proper time and to the required degree, Iprovide a rack 20 which may constitute an integral part of a verticallymovable bar 21, but which, in the present instance, is formed separatetherefrom for the purpose of providing for relative adjustment in themanner hereinafter explained. This bar which is rectangular in crosssection in the present instance, as seen in Fig. 1, is arranged to slideup and down in a guide 22 secured in suitable manner to the machineframe. The means for moving or reciprocating the bar 21 verticallycomprises a handle 28 arranged at one side of the machine and secured toa transverse shaft 24 which is in turn operatively connected through theseries or train of gears 25, 26, 27 and 2S with such bar 21, such barhaving a rack 29 which is adapted to engage with the last gear 28 of thetrain. It will now be understood that when the handle 23 is operated bydepressing the same from its normal position indicated in F ig. 2 thebar 21 will be elevated with the result that its rack 2O which is inmesh with the gear or pinion 14. will cause the latter, together withits arbor 5, to rotate so long as the gear la and the rack 2O are inmesh. lhen, however, the rack 2O passes upwardly beyond the range of thegear 14 and at the very moment of disengagement a second rack 30 at thelower end of the bar 21 will be brought into mesh with pinion 31, (Fig.3) to thereby move the arbor and templet longitudinally outwardlywithout any rotary movement of the arbor. This is accomplished by meansof operating connections between the lower rack 3G and the slidingframe. As herein shown, the rack 30 which may be made separate from thebar 21 so as to be adjustable relatively thereof is arranged to meshwith a pinion 31 whenever the bar 21 is elevated suiiiciently to presentsuch rack 30 thereto. This pinion is secured to one end of a transverseshaft or 'spindle 32, to whose other end is secured a pinion 33 arrangedto mesh with a rack 34 on the underside of the slide frame. It is nowobvious that after the rack 20 has passed beyond the range o-f the gear14 the rack 30 becomes engaged with the pinion 31, whereupon the solemovement of the arbor 5 is a longitudinal one and the junction betweenthe straight cut and the spiral cut is formed wit-h absolute accuracy,just as it is formed in the templetvS.

As above stated, the racks 20 and 30 are made separate from the bar 21and are adjustable relatively thereof. Referring first to theadjustability of the rack 20, the bar 21 is provided with a top cap 21ELwhich is secured to the bar in suitable manner, as by means of the screwbolts 21h, and through which passes the adjusting screw 20a, engagingthe rack 20, with the result that, as the screw is rotated in onedirection or the other the rack 20 is moved and adjusted accordingly. Inlike manner the lower end of the bar is provided with a bottom cap orplate 21C which is secured thereto in suitable manner, as by means ofthe bolts 21d, and through which passes the adjusting screw 30a,engaging the rack 30, with the result that, as such screw is turned inone direction or the other the rack is correspondingly moved oradjusted.

It will be understood that the blank stock 6 is held at its outer end insuitable manner,

as by means of a chuck 35 and that such blank is' operated upon at apoint between the end of the arbor and such chuck, as illustrated inFig. 1. The tool marked A is carried in a suitable tool-holder 3Gmounted in the hub of a post 37, which is stationary so far as movementlongitudinally of the f machine is concerned, the work in blank beingthe element movable in such direction. The tool-holder is arranged torotate within an inner sleeve or bushing 38 which is itself containedwithin an outer bushing 89 having screw-threaded connection therewith atits inner end, as clearly indicated in Fig. 4. rIhe tool-holder isrestrained against longitudinal movement wit-h respect to its sleeve 38by means of the circular flange 40 and also by the pinion 41 secured onthe outer reduced end of such tool-holder. Upon the inner sleeve 88 ismounted a ratchet wheel 42 and also a hand-wheel 43 for the purposehereinafter explained.

For the purpose of rotating the toolholder in automatic manner, Iprovide a segmental gear 44 pivoted intermediate its length upon asupport or bracket 45 rising from the main frame of the machine, whichgear meshes with the gea-r or pinion 41 and is automatically oscillatedin the sliding movements of the main slide which carries the templet. Tothis end, said slide is provided with an upwardly extending bracket 46on which is adjustably mounted a cam plate 47 having an irregular or camslot 48, which is arranged to coperate with a stud or roller 49projecting laterally from the free and extended end of the segmentalgear 44. It will be understood that when the main slide movesrearwardly, that is to the left in Fig. 2 in the operation of producinga coiler, the cam plate 47 is correspondingly moved to the left, withthe result that the segmental gear would be rocked downwardly and thepinion 41 correspondingly rotated, so that the face of the tool willalways be presented squarely to the cut at all times.

For the purpose of withdrawing the tool from the work after it hasreached the end of its cut and for advancing such tool to the work afterthe templet and associated parts, together with the blank stock havebeen retracted for the next operation or cut, I provide the followingmechanism. Upon al stud or bolt 50 on one side of the .tool post I pivotthe lower end of a yoke 51 which encircles the hub portion of the post37 and is provided at its upper end with an outwardly project-ing lug52, which receives through a transverse slot a pin or stud 53, asclearly shown in Figs. 1 and 4. This stud screws into the upper face ofthe outer sleeve or bushing 39 and passes through an angular slot- 54 inthe hub of the tool post.

This yoke is adapted to be automatically operated or shifted at oppositeends of the stroke of the main slide of the machine and in the presentinstance such means comprises adjustable bolts or screws 55 and 56,mounted in suitable manner upon said main slide frame and interposed inthe path of movement of the yoke portion 51 above its povotal point. Thearrangements of the parts and the angular formation of the slot 54 aresuch that when the yoke 51 is contacted by the screw or bolt 55 at theend of the outward or rearward stroke of the main slide frame, the outersleeve 39 and the inner sleeve 38 will be shifted outwardly, togetherwith the tool-holder and tool, so that the tool will be removed from thework at the time when the templet and associated parts are moved. backto normal or starting position. When the templet and main slide frameare thus restored to starting position and at the end of said movementthe other screw or bolt 56 will contact the projection on yoke 51 andwill shift the outer sleeve 39 in a direction the reverse of that causedby the screw 55 with t-he result that the tool will be advanced to thework. By preference and in the present instance, the screw or bolt iscarried at the outer end of a plate or bar 57 secured to the chuck 35and traveling therewith. The other screw or bolt 56 is carried upon aplate 58 which is adjustable upon the main slide frame.

It will be understood that the cut in the blank stock or coiler is notmade at one time but that a series of cuts are made until the requireddepth is obtained. For obtaining in automatic manner the proper feed ofthe tool for the successive cuts I provide suitable mechanism which, inthe present instance, consists of a ratchet feed between the slide frameand the inner sleeve 38. As hereinbefore stated, this latter sleeve isprovided with a ratchet wheel 42 and to impart to the same theintermittent and step by step feed, I provide a pivoted pawl 59 pivotedat one end at 60 to the bracket 46 and having its other end madehook-shaped or pro-vided with a ratchet tooth to coperate with theratchet teeth on the wheel 42. When the slide frame moves outwardly,that is to the left in Fig. 2, the pawl 59 rides freely upon the teethof the ratchet wheel 42, but upon the reverse movement of the slideframe such pawl engages a tooth on the ratchet wheel and causes arotation of the inner sleeve 38 and a consequent inward feeding of thetool to the extent represented by a one-tooth movement of the ratchetwheel. This inward feeding of the tool to the work is intermittent withevery stroke or movement of the main slide frame and such feedingcontinues until the proper or required depth of cut is reached.

After the groove has been formed in the blank stock, a cut-olf toolmarked B of usual and well known construction is advanced to operativeposition and at the same time the key 16 is moved inwardly to withdrawthe same from engagement with the gear 14 and to bring it intocooperative relationship with the pulley 1S, whereupon the arbor isrotated by means ot the pulley and the completed coiler cut ott from theblank stock.

Describing one complete movement or cycle of movement of the operatingpart-s and assuming that the parts are in the relative positionindicated in the drawings, the tool is presented to the work or blankstock ready to begin the spiral cut and the gear 14 is operativelyconnected with the arbor by means of the key, while such arbor isdisconnected from the pulley 18. At this time also the roller 9 occupiesits position at the outer end of the spiral cut or groove in thetemplet. wWhen the operator depresses the handle 23 the movement istrans mitted through the train of gearing to the vertical rack 20,thereby causing the vertical bar 21 to be elevated and the gear 14 to berotated. This rotation of the gear or pinion 14 provides for the desiredor necessary rotary movement of the arbor and of the blank stock, rwhilethe required longitudinal movement in the degree necessary Jfor theproper formation of the groove is aii'iorded by the templet which, byreason of its engagement or cooperation with the roller 9 withdraws theentire arbor and blank stock outwardly as permitted by the groove in thetemplet. At the moment when the roller 9 reaches the junction betweenthe spiral portion and the straight portion of the groove, or ratherwhen such portion is presented to the roller, the rack 2O has justpassed beyond the range of the gear 14 and the rack 30 has now becomeengaged with the pinion 3l and the pinion 33 thereby rotated to cause alongitudinal movement of the main slide trame through the medium of therack 34. The arbor and associated parts, together with the blank stockare now moved outwardly but without any rotary movement, inasmuch as thestraight. cut or groove in the coiler is be ing formed. In this mannerand by these means the coilers are not only produced as exactcounterparts of the templet, but the groove on the coiler is formed withabsolute accuracy, especially at the junction between the spiral and thestraight portion of the groove or cut. It will be understood that duringthe operation just described, the tool is automatically withdrawn fromthe work when the end of the cut is reached,-so as to be free from thework when the arbor is rem stored to its normal or starting position,whereupon in automatic manner the tool is advanced to the work and atthe same time, by reason of the ratchet feed, the tool is advancedslightly inwardly to make the neXt and deeper cut. l/Vhen the groove oreut has been formed on the coiler to the sufficient depth, the operatorwithdraws roller 9 from engagement with templet and manually shifts thekey 16 inwardly, withdrawing the latter from the gear or pinion 14 andcausing it to engage with the pulley 18, whereupon operative connectionis established between such pulley and the arbor for the rotation of thelatter in the operation of cutting oii'1 the coiler from the blankstock.
